Abstract

Abstract

By MCNP5 program, we used the Monte Carlo method to calculate the scatter contribution and neutron scattering distribution produced by different scattering bodies in experimental hall. The results show that the scattered neutron intensity decreases with the distance between the critical assembly and the measuring position at first, then increases near the hall walls, forming a W shape. The experiments are designed and conducted to verify the correctness of simulation results. The consistency of the calculated results and the measured results demonstrates the reliability of the calculated results.
